Special Symposium Honoring
Dr. Barbara Sulzberger
Join us for a special session in honor of Dr. Barbara Sulzberger, Friday, 6/13 from 10am-4pm in Salon D.
SS01 - Advances in Aquatic Photochemistry: A Symposium to Honor the Career of Dr. Barbara Sulzberger
Chairs: Yu-Ping Chin and Bettina M. Voelker
The purpose of this symposium is to celebrate the retirement of Dr. Barbara Sulzberger and to honor her achievements in the field of aquatic photochemistry. We seek papers examining photochemical and associated processes in aquatic environments, including the formation and effects of reactive oxygen species (ROS) and other reactive transients, photochemical effects on dissolved organic matter and other aspects of the global carbon cycle, and transformations of inorganic and organic contaminants. Papers are especially welcome in areas highlighting Barbara’s major contributions to our understanding of the cycling of carbon, metals, and contaminants in aquatic systems. These include mechanisms and ffects of sunlight-driven metal redox cycling, heterogeneous photochemistry, and the roles of iron and dissolved organic matter in the production of ROS.

Barbara Sulzberger received her diploma in chemistry and her Ph.D. from the University of Bern, Switzerland. Both her Ph.D. and subsequent post-doctoral research at The Royal Institution of Great Britain were related to photochemical solar energy conversion. After an appointment at Ciba-Geigy AG, Switzerland, she joined the Swiss Federal Institute of Aquatic Science and Technology (Eawag) in 1986, then under the direction of Werner Stumm. At Eawag, she headed a group conducting aquatic photochemical research until her retirement in July 2007. Her research interests include (i) effects of solar radiation on the redox cycling and chemical speciation of metals (iron, manganese, copper), (ii) roles of iron in light-induced transformations of organic and inorganic pollutants (atrazine, diuron, EDTA, chromate), (iii) effects of solar radiation on the chemical composition and bioavailability of dissolved organic matter (DOM), and (iv) roles of iron and DOM in the production of reactive oxygen species. Her research group substantially strengthened the competence in heterogeneous photochemistry at Eawag. The approach of her research group towards the identification of key processes occurring in sunlit aquatic systems combined laboratory experiments, including molecular-level methods, field studies, and mathematical kinetic modeling. Field studies included both freshwater and marine systems. In 1994 and 1995, she was a guest scientist at the Woods Hole Oceanographic Institution.
Barbara Sulzberger is the author or co-author of 9 book chapters and over 40 peer-reviewed articles published in international, high-impact journals. From 2002-2007, she was the editor-in-chief of the journal Aquatic Sciences - Research Across Boundaries. She continues being active as a scientist by (i) teaching a course “Environmental Photochemistry” for master students in “Climate Sciences” and in “Chemistry and Molecular Sciences” at the University of Bern, and (ii) being a member of the UNEP panel that assesses the environmental effects of ozone depletion and the interaction with climate change.
